1. Bedrock geology maps: These maps show the distribution and characteristics of different types of bedrock beneath the Earth's surface. They are useful for understanding the geological history of an area and identifying potential mineral resources.

2. Soil geology maps: These maps show the distribution and characteristics of different types of soil layers beneath the Earth's surface. They are important for agriculture, land use planning, and environmental management.

3. Hydrogeological maps: These maps show the distribution and characteristics of underground water resources, such as aquifers and groundwater flow patterns. They are important for managing water resources and planning for water supply and contamination issues.

4. Geophysical maps: These maps show the results of geophysical surveys, such as seismic, magnetic, or electrical surveys, which can provide information about the subsurface geology and potential resources.

5. Engineering geology maps: These maps show the distribution of geological features that may affect construction projects, such as faults, landslides, and soil stability. They are important for assessing the risks and challenges of building in a particular area.

6. Mineral resource maps: These maps show the distribution of mineral deposits and resources beneath the Earth's surface. They are important for identifying potential mining sites and assessing the economic potential of an area.

Types of Subsurface Geological Maps

1. Structure Maps:
- Depict the elevation or depth of a specific subsurface horizon or layer.
- Used to interpret geological structures such as folds, faults, and unconformities.

2. Isopach Maps:
- Show the thickness of a specific stratigraphic unit or formation.
- Aid in understanding sedimentary depositional patterns and subsurface reservoir distribution.

3. Cross Sections:
- Represent vertical profiles through the subsurface based on well data.
- Depict the stratigraphic relationships, structural features, and fluid distributions in a three-dimensional perspective.

4. Time-Structure Maps:
- Combine structural maps with seismic data to display the depth of a specific horizon at a given point in geological time.
- Used to track structural evolution and identify potential hydrocarbon traps.

5. Velocity Maps:
- Depict the seismic velocity of subsurface rock units.
- Aid in lithological interpretation and seismic imaging.

6. Pressure Maps:
- Show the distribution of subsurface fluid pressures.
- Used to evaluate hydrocarbon potential, reservoir connectivity, and subsurface hazards.

7. Porosity and Permeability Maps:
- Represent the distribution of porosity and permeability in subsurface formations.
- Critical for reservoir characterization and hydrocarbon flow modeling.

8. Geochemical Maps:
- Depict the distribution of geochemical properties in the subsurface.
- Used to identify hydrocarbon accumulations, mineral deposits, and groundwater contamination.

9. Depositional Environment Maps:
- Reconstruct the paleoenvironment and depositional processes that formed subsurface rock units.
- Aid in understanding reservoir characteristics and hydrocarbon exploration.

10. Integrated Subsurface Maps:
- Combine various types of subsurface maps to provide a comprehensive understanding of subsurface geology.
- Used for resource exploration, development planning, and environmental assessment.
